I 10 Claims. (ol flz -rcy This invention relates to new and useful improvements in a mechanical movement for chenille, embroidery and other machines.

The invention has for an object the construction of a mechanical movement which is capable terize the reciprocating mechanism by the pro vision of T-shaped members pivotally mounted at the center of their horizontal arms and having their vertical arms connected with the rack bars I to reciprocate them as the T- shaped members are oscillated, and anovel means for oscillating the T-sh'aped members. Still further the invention proposes to utilize vertical rods, arranged in lineflwith the ends of the horizontal arms in a Way so as to oscillate the T-shaped members when the rods are alternately moved upwards and downwards. j Still furtherjtheinvention proposes a novel mechanism for moving said vertical rods upwards and downwards. j I

Another object of the inventionresides in so constructing the mechanical movement that ad- .justme nts are possible to'control the distance through which the rack bars are reciprocated.

Still further the invention proposes the [construction of a device as mentioned which is sim ple and durable and which may be manufactured and sold at a reasonable cost. I I I For further comprehension of the; inv'entionj, and of the objects and advantages thereof, reference' will be had to the following description and accompanying drawings, and to theJappended claims in which the various novel features of the invention are more particularly set forth.

I Fig. 10 is a perspective viewof a portion ofone of the means for connecting the vertical rods with the ends of the horizontal arms of "the T- shaped members. i v Fig. 11 is-a'perspectiveyiewpf one of a plu ralityof abutment members used in conjunction with the vertical rods. l The mechanical movement in accordance with bar I2 and a lower horizontal rack bar-l3 ar ranged to reciprocate and adapted to turn a top gang-of gears l4 and a bottom gang of gears l5,- respectively'; These gears may'comprise'thebob bin or other gears ofa chenille manufacturing machine; or an embroidery machine, r other machinesof other types. In a chenille manufac-' ,turing machine it is customary to have-as many as 124' gearsineach of the upper and lower gangs of gears, for use in conjunction with the 124 nee "Each of the bobbin gears which the chenille material passes. Each gearis also provided with an opening I! throughwhich the needle passes. The details of the machine to whichgthe invention is applied forms no part herein and therefore such disclosure willnot-be given. The fundamental purpose ofthisinvention is to provide a novel mechanism" adapted" to oscillate 'a plurality of gangs of gears such as the gears I4 and I5, backwards and forwards. through predetermined amplitudes. The mechanical movement includes a top bracket l8 which is mounted upon the frame. l9, seeFig. 1, of the machine to which the mechanical movement is applied. This top bracket ,IB

hasside arms l8 uponwhich a pair of vertical straps are fixedly mounted. Arackbar I 2 engages through these vertical arms 20 so as to belimited to horizontal sliding only. A bottom bracket 22' is'also mounted on the frame l9 and tom rack'bar 'l3slida-bly engages through these straps23i" 1;

[A T-shaped member-24 is pivotally mounted at the center of itshorizontal arm on each of the brackets 18 and 22. A means is provide'd for the vertical arm of each of the T-shaped members base. pair of side arms 22 upon which a pair ofv vertical straps 23 are fixedly mounted. The bot-'- this invention includes an upper horizontal rack i in the vertical arm of the T-shaped member. As each T-shaped member 24 oscillates about its supporting pintle 28, its associated rack bar will reciprocate, in that the block 25 will be moved by the vertical arm of the T-shaped member. The block 25 is capable of sliding in the slot 21 ,to compensate for the arcuate path taken by the vertical arm of the T-shaped member in relay-1, tions to the horizontal pathtaken by .the--ra'ckbar.

A pair of vertical rods 30 and 3| 'arearranged in line with the ends of the horizontal arms of the T-shaped members 2-4 -.=and are 'slidably mounted to be reciprocated upwards and down-, wards. More specifically the upper portions of the rods 30 and 3|. pass through bearings 32" formed in an auxiliary bracket 32 which is mounted around the bottom portion of the 'top bracket I 8 by several holding screws 33. Intermediate portions of the vertical rods 30 and '3| slidably pass through bearings 34' formed in another auxiliary bracket 34 whichis mounted upon the upper'portion of the bracket 22 by several fastening screws 35.

A means is provided for each of the vertica rods 30 and 3| for connecting them to the-adjacent ends of the horizontal arms of the T- shaped members 24 to oscillate the T-shaped members when the vertical rods are reciprocated in :opposite directions. This meansincludes a U-shaped block 36 for each end of each horizontal arm of eachT -shaped member. Each U- shaped block'36 is mounted upon one or the other of the vertical rods 30 and 3| by-several set screws3l passing through theblock and abutting the vertical rod. The arms of each u -shaped b1ock36 engage above and below ablock 38 which is mounted on the end of the horizontal arm o f the T-shaped member. The arrangement is such that when the vertical arms 30 and! move vertically upwards and down-wards the 'T-shaped members will be oscillated with the blocks. 38 pivoting and moving laterally between the arms of the U-shaped blocks 36. t

A shaft 40 is rotatively supported through bearing portions 34* formed on the auxiliary bracket 34. A disc 4| is fixedly mounted on the-shaft 40 between'the bearing .portion "34 and at alocation between the vertical rods 30 and 3 I. This disc has a lug :portion 4W through which=set screws 42 engage *for accomplishingihe"attachment of the discon the'shaft. Eccentric *members 43 are mounted on opposite faces of the disc 4|.

The disc 4| is form'ed With'a pair 0f slots 44 formed on a diameter line thereof. Each-'of the slots '44 is surroundedby an elongated boss 45. These bosses 45 -are-arranged on opposite sides of the disc 4|. The eccentric members -"43-are adjustably mounted-upon the bosses '44. 'Thisis accomplished by cap screws 46 passing through the slots '44 and'threadedly engaging into the eccentric members 143. 'Thec'ap screws '43 may be loosened-and then the eccentric members .radially adjusted upon the disc4l. 1 H

Each eccentric member-43 is cooperative with an abutment member '41, which is adjustably mounted on'each of the'vertical'rods 3|] and 3|.

Each abutment member 41 is'fiXedly-kheld in adjusted positions by several-cap screws 48 which threadedly engage through one 'ofthe sidesthere- 20f" and abut the vertical rods.

tion of the eccentric members 43 whenthe disc 4| rotates.

A means is provided for rotating the disc 4|. This meansincludes a sprocket wheel5|l mounted on the shaft 40 and engaged by-a chain 5| engaging over'a driver sprocket wheel 52. This driver sprocket wheel may be synchronized with a portion of the machine to which the mechanic {Imovement is applied. I H The top bracket I8 is provided with a lug i8 having a'slot54 to assist in mounting the bracket "on the frame I9. The frame I9 has a complementary lug l9 forthis purpose into which a holding element which passes through the slot may engage. The bottom bracket 22 is provided.

with an intermediate lug 22Pand a bottom lug 22. These lugs are formed With elongated slots 53 through which fastening elements may engage. The lugs 22 and 22 are cooperative with complementary lugs i9? and |9 of fthe frame .|9. Fastening elements engage through slots '53 for assisting in securely holding the bracket in position on the frame 19.

I The operation of the device is as' follows;

The chain 5! will.:be driven continuou'slyflin one direction by the driver sprocket "52. The

chain will rotate the sprocket wheel'ififl continu- Y ously in one direction. 'This findire'ctlyrotates the disc 4| causing first one of the eccentricmembers 43 toengage one of the projecting 'lug ,Portions "41 of one of the abutment members T431. This moves one of the vertical rods downwards. The downward motion of the vertical rod is com municated to oscillate the T -shapedlme'mbers"24 '35 will oscillate the gangs of gears with which'they mesh. r

The amplitude of oscillation of gangsofgcars will" be controlledbyvaryi'ng the, positionslof the abutment members' i'l'upon the rods .30 and3l. These abutment members are moved upwards or downwards, as desired, tol'change the relationship 'with'resp'ect to the eccentric members (.43. ,The relationshipmay be changed so "that each eccen- 'tri'c member will -move each "of the abutment '1 members 41 through a'differentdistance. This controls themotion of the racks Hand 13. The I frictional resistance of the gang 'ofgears are depended upon to hold the racks'in various stationary positions, during "that period when "the eccentric m'embers 43' do not contact 'with' the lugsl! of theabutment members 441.

While I have illustrated'and' described the preferred embodiments of my invention, it is tobe precise constructions herein disclosed and the right is'reserved to all changes-and modifications coming within the scope of the invention asdefined in the appended cl aims.
